Gapless playback does not work when connected to a Chromecast Audio.
Using either a Nexus 5X running Android 7.0, or an ASUS tablet running Android 4.2.2.
Gapless works as expected with normal playback on the devices themselves.
Spotify version 188.8.131.522, Chromecast firmware version 1.21.74816
Thanks for that info @brokensitar!
We're afraid gapless playback isn't available in Chromecast Audio for Spotify, but we'll pass on your feedback to the right folks and let them know it's an option you'd like to see.
Let us know if there's anything else we can do for you, we'd love to help 🙂
